The second video is a music video by OK Go, a band I had never heard of, but whose synchronized performance on six treadmills is a sight to behold. The music's not too bad, either, if you like indie style pop rock. What I found most impressive is the whole 3 minute segment is done with one take. There are no camera cuts. [UPDATE: Apparantly I'm completely out of touch with today's pop culture. Several people have told me this video has been around for a while on TV. Since I don't have a TV, it was new to me.]
